Return All Values From Table If Query String Is Empty

Jan 1, 2010

I have a page that lists products from a table based on the querystring. So if I say foo.aspx?fam=1 all the products from family 1 will be listed. How can I make my code list all the values if query string is empty? My SQL command would have to be different...can't really see how I can do this.

<asp:SqlDataSource ID="ds_produtos" runat="server"
ConnectionString="<%$ ConnectionStrings:LocalSqlServer2 %>"
SelectCommand="SELECT DISTINCT [IdProduct], [Name], [Description], [IdFamily], [Price], [Stock] FROM [Product] WHERE ([IdFamily] = @IdFamily )">
<SelectParameters>
<asp:QueryStringParameter Name="IdFamily" QueryStringField="fam" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>

Facebook - Fql.query Method Returns Empty String

Jan 29, 2010

I have developed a web application 3 months ago to show facebook users by searching username. To access facebook, I have downloaded facebook dll and got application key, and secret key from facebook. My web application was working fine and displaying records from facebook. yesterday onwards, my application is not working fine. I could not get response when I search by name. I have tested the fql in the facebook testAPI tool online. That time i can get response. but the same fql i used in my appliation but it could not get response from facebook when I search by name. If i search by uid i can get response from facebook. here is my code.

facebook.Components.FacebookService fb = new FacebookService();
fb.ApplicationKey = "bfeefa69afdfe81975f0d6136ace3009";
fb.Secret = "9b672d682e1d8befd06382953fc2615b";
fb.IsDesktopApplication = false;
//the below fql gives response as xml.
//select name, profile_url from user where uid = '1730923544' -I can get response for this fql.
//the below fql does not give response as xml. But it gives empty string.
//the below fql does gives us response as xml when i try in facebook testAPI.
//select name, profile_url from user where name = 'Suresh Rajan' -I couldn't get response for this fql.
string s = fb.fql.query("select name, pic_square, profile_url from user where name = 'Suresh Rajan'");
if (String.IsNullOrEmpty(str1))
Response.Write("Empty Response");
else
Response.Write(str1 + " ");

how to search by name in facebook fql.

VS 2010 / Json Replace Null Values With Empty String?

Jun 1, 2012

If I have JSON like this and pass it to the engine I am using to create a PDF file, the word "null" appears on the PDF. This isn't really my example, but I googled "json replace null empty string" and this was a hit, which is a good representation of my data, also:

{
"relationship": {
"type": "relationship",
"id": null,
"followed_id": null
}
}

We use a rendering engine that creates a PDF from a fixed template and variable data in the form of a json string. But our customers don't want to read that the id is "null", they want to read that the id is blank. In my C# program, the json is just a string, so I can easily do something like this:

jsonString = jsonString.Replace("null,", ",");but the issue is I can't replace null-comma with a comma, because then it's invalid json.

how to I make the rendering engine *and* my customer both happy?

Query String Parameters With No Values?

Jun 28, 2010

I am trying to set up a page that has two behaviors. I'm seperating them by URL: One behavior is accessed via /some-controller/some-action, the other is via /some-controller/some-action?customize. It doesn't look like the Request.QueryString object contains anything, though, when I visit the second URL...I mean, the keys collection has one element in it, but it's null, not 'customize'. Anyone have any ideas about this or how to enable this. I'd like to avoid manually parsing the query string at all costs :).

Run A SQL Query With A List Of String Values Using The "WHERE [columnname] IN [values]" Format?

Mar 11, 2011

I have a SQL query I'm running in an ASP.NET page. The final parsed SQL needs to contain a list of string values in the WHERE [columnname] IN [values] format. For example, the final query might look something like this:

SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN ('ABC','DEF','GHI','JKL', /* etc */);

However, the string values in the WHERE clause need to be dynamic. Normally I use parametrized queries to make my code convenient and safe, so conceptually I'd like to do something like this:

String[] productCodes = { "ABC", "DEF", "GHI", "JKL" };
SqlCommand cmd = "SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN (@ProductCodes)";
cmd.Parameters.Add("@ProductCodes", productCodes);

However, this sort of functionality doesn't appear to exist in .NET. How should I go about implementing this? I could use a foreach loop on the array and run a query with a single value as a parameter for each value, but there could potentially be a hundred or so different values in the array and it seems like querying them separately would be very inefficient.

I've read another question where someone suggested a solution for strongly-typed int parameters, but that method would make me nervous about SQL injection when used with String values, especially since the client may very well be able to influence the input values.

How would you implement this query functionality?

EDIT with DB Details:

The database is SQL Server 2005.
